As spring approaches, gardeners are eager to prepare for a successful growing season. Focusing on key tasks like soil preparation, fertilization, and planting – or starting seeds indoors – sets the stage for a bountiful harvest.
With increasing daylight and rising temperatures, plants are emerging from their winter dormancy, making March an ideal time to get your garden ready. The risk of severe frosts diminishes, and the soil becomes workable and receptive to nutrients.
Nurturing the Soil: The Foundation of a Thriving Garden
Healthy plant growth begins with healthy soil, whether in traditional garden beds or raised planters. Most plants thrive in loose, nutrient-rich soil. If your vegetable garden soil is compacted or waterlogged after winter rains, now is the time to address it.
The goal is to achieve a crumbly structure, perfect for sowing seeds and transplanting seedlings. Loosen the soil with a tool like a garden cultivator, then refine it with a rake.
This aerates the upper soil layer and supports microorganisms, which break down organic matter like compost and leaf litter, making vital nutrients available to plants. Incorporate leftover plant debris from last year, chopping it up if necessary, to improve soil structure. This mimics natural processes where organic material is continuously recycled.
However, a vegetable garden isn’t a natural ecosystem. Plants are grown closely together and need to produce a good harvest. They require support and ideal conditions to thrive. Preparing the soil is the first step.
Nourishing the Soil: The Power of Compost
Enriching your vegetable and raised beds with nutrients is crucial. The question of whether to fertilize is easily answered: vegetables need nutrients to develop from seed to harvest. Fertilizing provides these essential nutrients, based on the plants’ needs.
A time-tested method, especially for beginners, is to enrich the soil with compost. If you compost yourself, apply finished compost to the beds. It should be well-rotted, dark in color, and crumbly in texture, typically after two years and annual composting.
You can also purchase finished compost, often available affordably from municipal composting facilities or garden centers. It’s practical for smaller areas and raised beds, but more expensive. Spread a few centimeters evenly over the beds and work it in with a cultivator or rake.
Supporting Natural Processes with Fertilizers
You can also use commercial fertilizers to supplement. These come in organic and mineral forms. Organic fertilizers consist of animal or plant substances, supporting soil life and improving structure like compost. However, microorganisms need time to break down these materials and develop nutrients available to plants.
Mineral fertilizers are industrially produced and provide nutrients in water-soluble salts, making them immediately available. However, relying on organic fertilizers is preferable.
Organic fertilizer or compost can also be applied to perennial beds. Simply work it into the surface.
Tip: Long-term, it’s better to promote a natural buildup of humus in your beds. Leave fallen leaves each year and mulch with grass clippings or chopped plant debris.
Planting Time: But Not for Everything!
March is the time to plant perennials and shrubs. The earlier, the better, even throughout the winter as long as the ground isn’t frozen.
You can divide and replant perennials now, even if shoots are already emerging. When buying new perennials, choose plants grown outdoors. Plants sold in greenhouses may have been forced and could be susceptible to cold snaps.
Tip: Buying from a perennial nursery ensures plants are adapted to local weather conditions.
Starting Seeds Indoors and Direct Sowing
Starting seeds indoors for tomatoes, cucumbers, and peppers is ideal in March. Choose a bright, cool window for optimal germination and growth. Avoid excessive heat, which can lead to leggy seedlings.
It’s often recommended to sow hardy vegetables like lettuce directly in the garden in March, but this is best done with caution. If the weather remains mild, direct sowing can be successful. Otherwise, wait until April for a better chance of undisturbed growth.
Pruning Roses and Shrubs: Last Minute or Just in Time?
Pruning trees and shrubs can be done throughout the winter. However, time is running out. You can prune fruit trees, roses, and formally shaped hedges now.
Major pruning is prohibited after March 1st under federal conservation laws.
Lawn Care: Getting Started in March
March is the time to begin lawn care. To achieve a lush lawn, consider dethatching, overseeding, and fertilizing. Dethatching removes thatch, allowing light and air to reach the grass. Overseeding fills in bare spots, and a starter fertilizer promotes new growth.
